Fluid sample collection system for pumped fluid source

A fluid sample collection system for directly collecting a fluid sample from a fluid source includes a fluid collector and a fluid line. The fluid collector includes (i) a sample vial including a sample vial body and a vial cap that is selectively coupled and sealed to the sample vial body; (ii) a collector body that defines a passenger vial chamber, the sample vial being positioned at least partially within the passenger vial chamber during collection of the fluid; and (iii) a cap access facilitator that is configured to engage a portion of the sample vial to enable a user to selectively couple the vial cap to the sample vial body to seal the sample vial so that the fluid is retained within the sample vial. The fluid line extends between the fluid source and the fluid collector to substantially directly transmit the fluid sample to the fluid collector without exposing the fluid sample to the ambient environment that surrounds the fluid sample collection system.
